Question about Joule Performance eSports RTX3090 II9

This PC is operated with a Corsair H100i processor water cooling system. The rest is done with normal "fans". It is not a complete water cooling system but simply for the processor.

But I would really be interested to know whether it is water-cooled or not, because that is a purchase criterion for me. @Digitec

and why doesn't it say "has purchased item"?
